SPECIFICATION forming part of Letters Patent No. 540,104, dated May 28,1895.

Application filed January 15, 1895. Serial No. 534,994- (No model.)

- To all whom it may concern.-

Be it known that I, JOHN G. KOUHOUP'I, of Jersey City, in the county ofHudson and State of New Jersey, have invented a new and ImprovedStone-Cutting Machine, of which the following is a full, clear, andexact description.

My invention relates to improvements in stone cuttingmachines; and theobject of my IO invention is to produce an extremely simple machine orrather an attachment to an ordinary trip hammer, which machine orattachment is adapted to rapidly split or cut stones and is especiallyadapted to form cobble- :5 stones or other small stone blocks, and whichmay be readily adapted so as to split ablock into any necessary numberof pieces.

To these ends my invention consists of certain features of constructionand combina- 2o tions of parts. which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the views.

Figure 1 is a side elevation of a part of an ordinary trip-hammerprovided with my improved attachments. Fig. 2 is a sectional plan on theline 2 2 of Fig. 1. Fig. 3 is an inverted plan view of a die adapted tosplit a stone into four parts. Fig. 4 is an inverted plan of a die whichis adapted to split a stone into three parts, and Fig. 5 is an invertedplan of a die which is adapted to divide a stone 5 into two parts.

The drawings illustrate an ordinary trip hammer frame 10 having avertically reciprocating plunger 11, and the usual anvil 12, but nomechanism is shown for actuating the plunger as this mechanism hasnothing to do with my invention and any usual means may be employed. Theanvil is shown provided with dovetailed cross grooves 13 which cross theanvil face at right angles and which are adapted to receive the knives 14, the edges of which project a little above the face of the anvil, andthe knives are preferably flattened at their outer ends to form handles15 by grasping which any knife may be readily inserted or removed.

The knives 14 are broad at the base so that they can well withstand ashock of a blow, and the knives meet at the center in order that theymay be conveniently arranged, as described below, to divide a stone intothe necessary number of pieces.

Arranged diagonally between the knives 14 are springs 16 which arefastened at their inner ends, and the free ends of which extend upwardto about the level of the knife edges, these springs serving as supportsfor a stone which rests on them as well as the knives, as shown bydotted lines in Fig. 1, and is thus steadied so that a descending diemay strike evenly upon it. The device may be used '6 without thesespring stone-holdersif desired, without affecting the principle of theinvention.

If a stone is to be divided into four parts the four knives 14 arearranged in the anvil, as shown in Fig. 2, but if the stone is to bedivided into three parts one of the knives is removed and if it is tobedivided into two parts, two of the knives are removed. This arrangementprovides for shaping rectangu- 7 lar blocks, but it will of course beunderstood that the anvil may be provided with any necessary number ofknives without departing from the principle of the invention.

In connection with the anvil and knives, 8o

dies are used, which are secured to the plunger 11 and which havecutting edges corresponding to the knives on the anvil. The die 17 hasconsequently four cutting edges 18 to correspond with the four knives14, and the die is adapted to be secured to the plunger 11 by a bolt 17,and when used a stone is placed upon the four knives 14 and the plungerdescending causes the die to give a sharp blow to the stone and theeffect of the 5 edges 18 on the die and the blade 14 is such as to causethe block to-split into four parts.

If, however, a stone is to be split into three pieces, one of the knives14 is removed and a die 19 used, which die is provided with cuttingedges 20 and 21, the former extending entirely across the face of thedie and the latter half way across and at right angles to the former, sothat the cutting edges will align with the three knives on the anvil,10o

while if a stone is simply to be divided into two parts a die 22 is usedwhich has a cutting edge 23 extending diametrically across it, and inconnection with this die only two knives 14 are used which alignlongitudinally.

It will be seen from the foregoing description that the machine may bereadily adjusted to cut stones into any necessary number of parts, andit is not usually necessary to change the knives 14: and dies often,because the stones which are large enough to split into four pieces, mayfirst be used, after which the machine may be made to split three piecestones and a quantity of these fashioned, and then the still smallerstones may be split into two parts.

Having thus described my invention, 1 claim as new and desire to secureby Letters Patent 1. The combination of the frame carrying a holderslocated substantially diagonally between the slideways, as set forth.
